Description
Summary:Sugar import volume in Indonesia always increases from year to year. It is caused by increasing sugar consumption of Indonesian people from year to year. Despitefully, the national sugar production always decreases because of decreasing in sugarcane planting areas and productivity such as the decline of the rendement. Declining of rendement is caused by unoptimal design and operation of sugarcane crusher machine and also in the plant treatment. The solution to avoid rendement declining due to unoptimal design of sugarcane crusher machine can be done by redesign it. The redesigned machine is expected to increase the juice sugar volume 5% more than the previous model of existing machine. Machine is designed using double action system which uses two pairs of rollers to increase the juice sugar. Sugarcane crusher machine that is already in the market uses a single action system which using a pair of roller. Single action system can be represented by disabling a pair of roller in the double action system. The production capacity of the designed sugar cane crusher machine is about 900 kg/hour. Based on the results of 10 times crushing from single action to double action system, it is achieved that the increasing of PS 77 and BL sugarcane are 31.19% and 16.86% respectively. From the economic analysis is found that benefit cost ratio (B/C) is 1.18 for breakeven point in Rp. 3.956.044,00 with payback period of 2.3 years and the return on investment (ROI) is 17.88%.
